Researchers at Woodend Hospital in Aberdeen, Scotland used a new form of magnetic resonance imaging to collect images from 22 healthy volunteers, who assumed three different sitting positions: slouching posture in which the body is hunched forward, an upright 90-degree sitting position, and a relaxed position where the subject reclined backward 135 degrees. They concluded that the reclined position is the best, and the forward slouch the worst.” From the article: “‘We were not created to sit down for long hours, but somehow modern life requires the vast majority of the global population to work in a seated position,’ Dr. Bashir said. ‘This made our search for the optimal sitting position all the more important.'”
